Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a gutter channel refluence filling device, which can solve the problem that drainage is influenced by the fact that a check valve in a drainage hole of a gutter channel is easy to block in the drainage process in the related art.
Referring to fig. 2, the backflow irrigation device of the water flowing channel mainly comprises a water flowing component 1 and a backflow irrigation component 2, wherein the water flowing component 1 comprises a water flowing channel 10 and a water drainage hole 11 arranged at one end of the water flowing channel 10, the backflow irrigation component 2 is arranged above the water drainage hole 11, and the backflow irrigation component 2 is used for blocking sewage which flows backwards into the water drainage hole 11 through a road surface in the driving process of a vehicle and is used for reflecting the sewage which flows backwards to the surface of the backflow irrigation component and then discharging the sewage again from the water drainage hole 11.
Specifically, the gutter channel 10 is disposed below a windshield of the vehicle and parallel to a width direction of the vehicle body, and is configured to collect accumulated water flowing through other structures on and near the windshield, and the drain hole 11 is generally disposed below one end of the gutter channel 10 close to the door and is configured to drain the accumulated water collected by the gutter channel 10, so that the drain hole 11 is communicated with the outside, and a wheel cover structure is disposed below the drain hole 11. The wheel cover structure is mounted at the lower part of the vehicle body, the wheel cover plate in the wheel cover structure is concentric with the wheel and can play a good role in preventing muddy water, however, although the wheel cover structure exists, when the vehicle passes through a water accumulation road section in rainy days or runs on a road surface with a lot of potholes and poor road conditions, a lot of sewage is brought by the speed of the wheel, the wheel cover structure can only block one part of the muddy water, and the rest part of the muddy water can hit the vehicle bottom structure. The drain holes 11 are close to the wheel casing structure and are communicated with each other, so that when a vehicle passes through a water accumulation section and a road surface with a lot of pits at a certain speed, a part of sewage carried up by the wheels often enters the launder 10 through the drain holes 11.
In the running water tank reverse-filling device, the reverse-filling component 2 is arranged above the drain hole 11, so that when a vehicle runs in a rainy day and encounters a water accumulation section or a pothole with accumulated water, sewage reversely filled into the drain hole 11 through a road surface is effectively blocked, specifically, when the sewage reversely filled into the drain hole 11 is driven by wheels to continuously move into the drain hole 11 and is contacted with the surface of the reverse-filling component 2, the reverse-filling component 2 can purposefully reflect the sewage on the surface of the reverse-filling component and re-discharge the sewage from the drain hole 11, so that the sewage reversely splashed from the road surface is prevented from reversely flowing into the running water tank 10 through the drain hole 11, compared with the prior art that the reverse-filling of the sewage during running of the vehicle is inhibited by arranging the check valve 4 in the drain hole 11, the reverse-filling component 2 can ensure that the water collected in the running water tank 10 is smoothly discharged from the drain hole 11, the anti-backflow check valve can effectively prevent sewage on the road surface from flowing back into the drain hole 11, solves the problem that the check valve 4 is frequently blocked, greatly improves the use feeling of users, skillfully solves the problem that the drain hole 11 is easy to block during drainage and backflow, and saves the manufacturing cost to a certain extent.
Further, as shown in fig. 1 and 3, the reverse irrigation assembly 2 includes a first inclined plane 20 and a second inclined plane 21 which are arranged along a direction from the vehicle head to the vehicle tail, the first inclined plane 20 is a plane and is inclined from bottom to top along a direction away from the vehicle head, the second inclined plane 21 is an arc-shaped plane and is protruded along a direction close to the vehicle head from bottom to top, and an adjacent end of the second inclined plane 21 and an adjacent end of the first inclined plane 20 are connected and transited through an arc. In particular, because the wheels have a fixed rotation direction during the running process of the vehicle, therefore, due to the driving direction of the wheels, when the wheels pass through the water accumulation area or the hollow area, the sputtering direction of most of the sewage carried by the wheels is inclined towards the vehicle head, and therefore, the first inclined surface 20 is inclined from bottom to top along the direction far away from the vehicle head, which functions to block most of the sewage, which is carried up and backwardly flowed into the drain hole 11 by the rotation of the wheel, and when the sewage is contacted with the first inclined surface 20, since the first inclined surface 20 is a plane having a specific inclination angle, it is possible to purposefully reflect the contaminated water, most of the sewage is discharged from the drain hole 11 again after being reflected, and the sewage reversely poured into the drain hole 11 is effectively prevented from entering the launder 10.
When the vehicle adopts different speeds and passes through water accumulation areas or hollow areas with different depths, the splashing angles of the sewage reversely poured into the drain holes 11, which are brought up by the rotation of the wheels, are different, generally no matter the vehicle speed, most of the splashed sewage inclines towards the direction of the vehicle head due to the rotation of the wheels, and when the vehicle speed is lower, the inclined angle between the splashed sewage and the horizontal plane is smaller, so that water entering the drain holes 11 is correspondingly smaller due to the smaller inclined angle, and when the vehicle speed is higher, the inclined angle between the splashed sewage and the horizontal plane is larger, and at the moment, the splashing direction is closer to the right-angle vertical degree, so that the water entering the drain holes 11 is correspondingly larger. In addition, when the sewage passes through deeper places with accumulated water, the inclined included angle of the sputtered sewage is relatively increased, the water phase entering the drain hole 11 is subjected to a large amount of strain, the sewage sputtered in the direction inclined to the vehicle head is also a small part of the sewage sputtered in the non-directional direction, and the sputtering amount and the sputtering angle of the sewage are in direct proportion to the vehicle speed and the wading water depth. Further, an included angle between the first inclined plane 20 and the vertical plane is defined to be 40-50 °, and this angle range can satisfy the reflection of the sewage reversely flowing into the drain hole 11 when different vehicle speeds and different water accumulation depths are met as much as possible, and in addition, in order to prevent the first inclined plane 20 from splashing the sewage into the gutter 10 in the process of reflecting the sewage, from the perspective of structural design, the projection of the first inclined plane 20 on the horizontal plane is located in the drain hole 11, and the ratio of the length dimension of the projection of the first inclined plane 20 on the horizontal plane in the direction from the vehicle head to the vehicle tail to the length dimension of the drain hole 11 in the corresponding direction is 1: 2 to ensure that the first inclined surface 20 does not splash into the flume 10 when reflecting the sewage contacting the surface thereof. Most of the sewage entering the drain hole 11 is in the direction towards the vehicle head, so that relatively less sewage in other directions exists, but the sewage also exists, so that the second inclined surface 21 is an arc-shaped surface and is in arc connection transition with the adjacent end of the first inclined surface 20, the shape of the whole formed by the second inclined surface and the first inclined surface is similar to a U shape, the arc-shaped second inclined surface 21 can be matched with the first inclined surface 20 to finally reflect and return the sewage to the drain hole 11, a small part of the sewage reversely flowing into the drain hole 11 in other directions can be well blocked, and the arc-shaped surface is easier to manufacture and form in terms of manufacturing process and cost.
Furthermore, because the water has a relatively strong fluidity, when the sewage backwardly flowing into the drain hole 11 by the rotation of the wheel contacts the first inclined surface 20, most of the sewage is reflected by the first inclined surface 20 and the second inclined surface 21 and re-enters the drain hole 11, and a small part of the sewage is not successfully reflected and flows down along the inner surface of the backwardly flowing component 2 under the action of the gravity of the sewage, so that the small part of the sewage entering the drain hole 11 can be re-flowed back into the drain hole 11, a plurality of grooves are respectively arranged on the inner surfaces of the first inclined surface 20 and the second inclined surface 21, the grooves are respectively arranged side by side along the width direction of the vehicle at intervals, and the depth of each groove is not more than 1 mm. Specifically, since the depth of each of the grooves is shallow, the reflection of the first inclined surface 20 and the second inclined surface 21 to the sewage on the surfaces thereof is not affected, and the grooves arranged side by side are used as diversion grooves for diverting a small part of the sewage which is not reflected to flow back to the drain hole 11 again.
Furthermore, from the viewpoint of reflection and structural design, in order to prevent the sewage reflected by the first inclined surface 20 and the second inclined surface 21 from flowing into the gutter channel 10, the projections of the whole of the first inclined surface 20 and the second inclined surface 21 on the horizontal plane are located in the drain hole 11, and therefore, this indicates that the drain hole 11 still has an area that cannot be blocked by the first inclined surface 20 and the second inclined surface 21, and in order to almost completely re-drain the sewage reversely flowing into the drain hole 11, both sides of the first inclined surface 20 and the second inclined surface 21 respectively extend outward along the edge contour thereof to form third inclined surfaces 22, and the projections of the third inclined surfaces 22 and the first inclined surface 20 and the second inclined surface 21 on the horizontal plane can cover the drain hole 11. Specifically, the third inclined surfaces 22 are respectively disposed on two sides of the first inclined surface 20 and the second inclined surface 21, and the third inclined surfaces 22 can be used for making up a blocking blind area of the first inclined surface 20 and the second inclined surface 21, so as to ensure that almost all sewage reversely filled into the drain hole 11 is re-reflected into the drain hole 11 under the combined action of the first inclined surface 20, the second inclined surface 21 and the third inclined surface 22 and then discharged.
Further, from the principle of reflection, each of the third inclined surfaces 22 is inclined in a direction away from the first inclined surface 20 and the second inclined surface 21 toward the drain hole 11, so as to ensure that the sewage reflected by the third inclined surface 22 can flow out after returning to the position of the drain hole 11, and in order not to obstruct the drainage of the flume 10, the distance between one end of the third inclined surface 22 close to the water discharge hole 11 and the water discharge hole 11 is not less than 30mm, that is, the distance between the end of the third inclined surface 22 close to the launder 10 and the launder 10 is not less than 30mm, so as to ensure that the water in the launder 10 can smoothly flow into the drain hole 11, in addition, most of dust, dead leaves and other garbage enter the drainage hole 11 through the water flowing groove 10, and the distance between the third inclined surface 22 and the water flowing groove 10 is kept large enough to ensure that no blocking point is formed at the position.
Further, when a vehicle runs or the weather state is severe and rainwater is large, the water flow speed in the launder 10 may be rapid, branches with small leaves and the like may be easily blown into the launder 10 along with strong wind in severe weather, and when the water flow in the launder 10 is more rapid and fluctuated, garbage in the water flow is easily blocked in a channel, so as to ensure the smoothness of the water flow in the launder 10 as much as possible, therefore, the edge profile of the cross section of the launder 10 is designed into a petal shape, which can play a role of better drainage, ensure the smoothness of the water flow, and eliminate the blocking point. In addition, the water flowing groove 10 and the third inclined surface22 is formed between adjacent ends thereof and has an area ranging from 14 to 16cm2。
Furthermore, in order to avoid as much as possible that the sewage on the road surface is reversely poured into the drain hole 11 by the rotation of the wheel, the drain hole 11 is designed to be in a circular truncated cone shape under the condition of not influencing normal drainage, the size of the drain hole is gradually increased along the direction close to the water flowing groove 10, the water in the water flowing groove 10 is favorably drained into the drain hole 11 as much as possible, the sewage reversely poured into the drain hole 11 by the rotation of the wheel is also reduced as much as possible, and animals such as mice and the like can be placed into the vehicle through the pores by the design of small outlet. In addition, because the sewage after back irrigation contains soil and has more dirt, in order to prevent the sewage from adhering to the inner walls of the drainage holes 11 or the water flowing grooves 10 to influence the subsequent drainage, the inner walls of the drainage holes 11 and the water flowing grooves 10 are coated with a fluorocarbon coating.
Further, a first connecting piece 30 is arranged at one end of the first inclined plane 20, which is far away from the second inclined plane 21, a second connecting piece 31 is arranged at one end of the second inclined plane 21, which is far away from the first inclined plane 20, and the first connecting piece 30 and the second connecting piece 31 are jointly used for fixing the first inclined plane 20 and the second inclined plane 21 with the drain hole 11. Specifically, the first connecting member 30 and the second connecting member 31 are both of a snap-fit structure, and are snapped into the drain hole 11, so that the first inclined surface 20 and the second inclined surface 21 are fixedly connected with the drain hole 11 on the premise of not affecting drainage.
The backflow device of the water flowing tank is reversely buckled right above the drain hole 11, the first inclined surface 20 designed by a specific inclination angle is mainly used for reflecting most of sewage reversely poured to the drain hole 11 so that the sewage is discharged again through the drain hole 11 after returning to the position of the drain hole 11, the second inclined surface 21 and the third inclined surface 22 are used for further blocking a small part of sewage reversely poured from other angles on the basis of the first inclined surface 20 and performing corresponding reflection, and the sewage is discharged again through the drain hole 11 after returning to the position of the drain hole 11 again, so that the function of assisting the first inclined surface 20 is achieved. The structure of the counter-irrigation device of the water flow channel has lower cost, can be directly formed by injection molding, and is simple to manufacture; secondly, the maintenance convenience is good, the assembly process is convenient, the reliability is high, and the drainage failure of the launder 10 caused by garbage congestion is not easy to happen; finally, most importantly, the sewage flowing back through the drain hole 11 can be effectively prevented from entering the flume 10 according to a specific structural design, on the basis, the entered sewage can be accurately reflected to the position of the drain hole 11 again and discharged again, the overall structural design is ingenious, and the problem that the drain hole 11 is easy to flow back into water is basically well solved.
